These aired back-to-back on Saturday mornings, ca. 1975/'76. I didn't miss a week. I liked how, in Shazam, the old guy and the kid used to just drive around in that god-awful Winnebago. Neither had jobs; and it was never really explained how, since they weren't working, they were able to fill the gas tank up... Of course, their wardrobes never changed, so that part was kind of believable. I don't remember Isis that much, but she was a pretty groovy chick. I think her character was a teacher, when she wasn't transformed into Isis. At least she had a job...
